Donovan continues to experience concussion symptoms, Ryan Divish of The Seattle Times reports.
Donovan has still felt concussion symptoms like nausea, fatigue and dizziness while participating in pregame workouts, and he will not be cleared to play until he can make it through one of those workouts free of symptoms. The 29-year-old has been sidelined since he was hit in the head by a baseball prior to a game against the Cubs on Aug. 22.
